Description

Technical Field

[0001] The utility model relates to the technical field of machining tools, in particular to a new type of drill reamer which is firmly installed. Background Art

[0002] A drill reamer is a cutting tool that combines the functions of a drill and a reamer. It is used to drill holes in workpieces and perform finishing of holes. It can perform preliminary drilling like a drill and finish holes like a reamer to improve the accuracy and surface quality of holes. However, existing drill reamers still have defects and deficiencies in some aspects that need to be improved:

[0003] For example, a drill reamer with application number: CN202122651753.7 comprises a base having a shank portion and a cutting portion, wherein the end face of the cutting portion away from the shank portion is a conical surface, and a transverse edge and a plurality of cutting edges are respectively arranged on the conical surface, and a plurality of secondary cutting edges are arranged on the peripheral surface of the cutting portion, wherein the transverse edge is located at the center of the cutting portion, and the cutting edge extends along the generatrix of the conical surface, and the cutting edge comprises an oblique edge and a main cutting edge connected to each other, and a plurality of blades are arranged on the cutting portion, and the main cutting edge and the secondary cutting edge are both formed on the blades. The drill reamer of this patent is designed with a transverse edge, so that the drill reamer has a drilling processing capability, and combined with the arrangement of the main cutting edge and the secondary cutting edge on the blade, the drill reamer can realize two processing modes of drilling and reaming at one time, thereby avoiding the increase of processing time and cost due to repeated processing, and the cutting edge is two connected to the two opposite sides of the transverse edge, which can make the tool structure simpler on the basis of ensuring the processing effect. The setting of the angle range between the cutting edges on both sides can form a centering effect during the processing and prevent the tool from swinging. The secondary cutting edge on the side of the blade is a cylindrical edge band, which can reduce the deformation of the hole through the extrusion and friction of the cylindrical edge band on the wall of the processed hole, and can ensure the dimensional accuracy, roundness and smoothness of the hole.

[0004] The drill reamers in the above documents are mostly fixed by threaded connections during installation. The drill reamers may become loose during use, resulting in unstable installation, thus affecting subsequent processing. At the same time, the outer sides of the existing drill reamers are mostly not treated with wear resistance and corrosion resistance, and the service life of the drill reamers is low.

[0005] Therefore we propose a new type of drill reamer which is firmly mounted to solve the above mentioned problems. Utility Model Content

[0006] The utility model aims to provide a new type of drill reamer with firm installation, so as to solve the problems in the above background technology that the drill reamer is not firmly installed, is easy to loosen, has not been wear-resistant and anti-corrosion treated, and has a short service life.

[0007] To achieve the above object, the utility model provides the following technical solutions: a new type of drill reamer with firm installation, comprising a fixing seat, a mounting groove is provided on the fixing seat, and a drill reamer body is nested and installed inside the mounting groove;

[0008] A first docking groove, wherein the first docking groove is provided inside the drill reamer body, and a second docking groove is provided below the first docking groove;

[0009] The anti-oxidation coating is coated on the outer side of the drill reamer body.

[0010] Furthermore, a fixed plate is fixedly connected to the outer side of the drill reamer body, and a slide groove is provided on the fixed plate, and two groups of the slide grooves are provided in an arc shape.

[0011] Furthermore, the opening length of the slide groove is greater than the opening length of the first docking groove, and the slide groove is located directly above the first docking groove.

[0012] Furthermore, a threaded body is provided on the drill reamer body, and the outer side of the threaded body is threadedly connected to a threaded block, and the lower end of the threaded block is fixedly connected to a docking block.

[0013] Furthermore, the docking block is in an "L" shape, and the docking block passes through the slide groove and is nested and docked to the inner sides of the first docking groove and the second docking groove.

[0014] Furthermore, the anti-oxidation coating is made of TiSiN nano-coating and CrAlN nano-coating, and the TiSiN nano-coating and the CrAlN nano-coating are alternately deposited on the outer surface of the drill reamer body, and the outer side of the anti-oxidation coating is coated with a wear-resistant coating.

[0015] Furthermore, the wear-resistant coating is a boron nitride hard coating and an aluminum oxide hard coating, and the wear-resistant coating completely wraps the anti-oxidation coating.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The user can connect the drill reamer body to the required equipment through the installation slot on the fixed seat, and the preliminary installation of the drill reamer body can be completed at this time;

[0018] 2. When the drill reamer body is initially completed, the slide groove on the fixed plate outside the drill reamer body corresponds to the position of the first docking groove. At this time, the user can rotate the threaded block along the threaded body and dock the docking block on the lower side of the threaded block to the inside of the first docking groove. At this time, the threaded block can be more stably docked under the threaded connection of the threaded body, thereby increasing the firmness of the installation of the drill reamer body;

[0019] 3. When the docking block is docked and installed in the first docking groove, the threaded block can be continuously rotated so that the threaded block drives the docking block to rotate in the first docking groove and the inner end of the docking block is rotated into the second docking groove. At this time, the second docking groove will further limit the fixed position of the drill reamer body, thereby improving the firmness of the installation of the drill reamer body.

[0020] 4. The wear-resistant coating is coated on the outer surface of the drill reamer body. The wear resistance of the outer surface of the drill reamer body can be improved through the double-layer design of the wear-resistant coating's own boron nitride hard coating and aluminum oxide hard coating;

[0021] 5. The anti-oxidation coating is coated on the outer surface of the drill reamer body. The anti-oxidation coating's own TiSiN nano-coating and CrAlN nano-coating improve the high-temperature oxidation resistance of the drill reamer body to a certain extent, thereby further improving the service life of the drill reamer body.
